Pearson correlation coefficients among the infection-responsive genes
The uncentered Pearson correlation was used to calculate correlation coefficients among the 936 genes showing differential expression between 0 hpi (T0) and 18 hpi (T18) in all three plant genotypes. The first three columns/bottom three rows indicate genes having a significant negative correlation between gene expression levels at T0 versus T18 for the three genotypes, showing consistent changes on gene expression (either induction or repression). The first three columns/top three rows and last three columns/bottom three rows indicate high significant positive correlations of gene expression levels among the three genotypes in uninfected (T0, top left corner) or infected (T18, bottom right corner; P < 0.0001).
